Tou/ZZ whom it may concern:

Be it known that we, WILLIAM YOUNG, re-

^ siding at 533 Bickershaw Lane, WILLIAM CLARK, residing at 523 Bickershaw Lane, and HENRY GREEN, residing at Hurdley Field House, Bickershaw, Wigan, in the county of Lancaster, En land, subjects of the King of Great Britain, ave invented new and useful Improvements in` Coal Cutting or I/Vinning Ias Machines, of which the following is a speciication.

This invention has reference to coal cutting or winning machines of the type actuated by {mid-pressure, and relates principally 'to carriages for such coal-cutting machines -dles in the rear, and the machine when in actual use rests upon boards arranged at an anglev and supported by trcstles or other- Wise. The operator squats in the rear, with his hands n the handles and his legs disposed on either side of the machine, the working of which he controls and directs. Working the machine in this way is a more or less arduous task for the operator who is backing up and controlling the machine,

. while the transport or carrying about of the machine, boards, and trestles is a by no means easy task in the mine. In addition to this, themachine cannot be as smartly and "easily handled as is desirable. f

According to our invention we propose to entirely dispense with the usual wheels at present attached to the Ingersoll machine and to mount the machine upon a carriage or traveling base and in sucha manner as will 'permitofthe machinev having a universal lmovementand, in addition, We provide for a vertical and horizontal movement of the coal cutting or winning machine with respect to such carriage or traveling base.

The invention will -bc fully understood from the detailed 4description which we now" give, such description being drafted with regard to the annexed two sheets' of drawings, in whichl'On Sheet 1, Figure 1 shows a side elevation Iof'our carriage supporting a percussive coalwinning machine of the Ingersoll type, the wheels of the carriage being shown engaging the rails of a track sue,n .f is used for the or' dinary ohngual trucks in the mine. Fig. 2.is a transverse 'section of Fig. l, taken on the line X X. On Sheet 2, Fig. 3 shows a plan view of the carriage. Fig. 4 is an enlarged detail view of one form of ratchet mechanism suitable for rotating the screwed sleeve.

As already stated, we dispense alto ether with the usual wheels at present attac ed to the Ingersoll machine, and we mount theeoal-winning machine M u on a shiftable. carriage or traveling base or preferably upon a structure or platform C, adjustable along said carriage or traveling base B. This shiftable carriage or traveling base'B is provided with wheels of-a suitable description to allow of the carriage being wheeled 'about the mine. In the drawings the carriageor traveling base B is of a rectangular shape and is constructed of wrou ht-iron or steel side lengths I) of a channe or other section,` the end members b being likewise of channel or other section, the parts being firmly riveted or bolted together. ture or framework B carries orv has secured This rectangular structhereto short axles c, which carry flanged wheels c.. In any case the ian'ged wheels c engage the usual track-rails d 1n the mme,

and so the carriage is transported.

As already stated, thepercussivelnachine M is mounted upon a structure or platform C, carried by the carriage or traveling base, and this structure or platform, as shown in the drawings, consists of side plates c, to which are firmly riveted or bolted strips of angleiron a, thehorizontal webs of which rest uplon the side members I? ofl the carriage, w ile a iiat base-plate e2 is also firmly secured IOO to the sideplates in such a manner that its extended edges bear against the bottom of the side members of the carriage. lt is thus seen that the angle-franse and the edges of the base-plate e2 form a slide which iolds and also accurately guides the structure or platform C when same is adjusted along 'the carriage or traveling base. The eide plates' e e are firmly connected together at the top by a plate e3, the whole cf the, combined members e, e, e', e', e, and e3 forming the structure cr movable platform C. it willbe obvious that the design of this movable platu form may be considerably varied so long as a firm structure is designed provided with slides tc'engage the side members of the carriagepand we dojnot wish to confine ourselves to the particular design shown.

lReturning to the percussive machine M, this has flanges or shaped brackets, such as g, which may form part of the coal-winning machine Vor be separately secured thereto.

`ln the said flanges or shaped brackets we form bearings cr steps, the said bearings or steps accommodating trunnions h or other axial support formed on a rotatable cap 72, which rests on and is carried by the upper extremity)T of a screwed sleeve i; rl`he trun. nions or axial su port allows of free movement of the mac -ne M in a vertical plane with the trunnions or axial support as center, while, owing to the cap k being rotatable, a sluing or horizontal movement of thema chine is also ermissible, and this in any plane which t e inclination of the machine u on its trunnions will allow. To permit of t e cap JL, and consequently the machine M,

being raised or lowered bodily, we provide aA vertical screwed shaft j, the lower end of which is firmly secured to the baselate e2 or otherwise to the structure or plat 'crm C,

, and this screwed shaft engages the screwed sleeve i, so that when the sleeve is rotated it .sets up or lowers the cap h, and conse quently the machine M. To actuate the sleeve i, aratchet motion Z, such as is clearly shown in the detail view, Fig. 4, may be used, and such ratchet motion may have a socket Z for insertion of an actuating-lever. (See also Fig. 2.) The ratchet device shown in Fig. 4 has a notched ring Z2 firmly secured to the sleeved, and a pivoted pawl Z3 mount ed in the jawed end of-the handle-socket, a spring-pressed' catch Z4 pressing on one or other of theangular facesvof the pawl. By acting on the pawl either one or the other of its operative legs may be thrown into engagement with a notch in the ring Z2, so that thesleeve i can be rotated in either direction. It will be obvious that the handle is moved back and advanced tc edect raising and lowering according to the setting of the pawl Z3,

seater Yaction of a brace. v

lt has been vclearly v explainedthat'the 'the detent motion being 'somewhatlikeithe percussive machine is carried upon-thestructure or platform C, 'andthis platform'y or structure is adjustable upon'the carriage por,

traveling base B, and to .obtain this traverse of the structure or platform weuse a screwed shaft m,.mounted inbearings'in the Y end members of the carriage or traveling base. ln ther .drawings the said screwed shaft m engages a nut formed' in the base of the screwed shaft j; but the -nut may be otherwisesecured to the Amovable structure or platformv C. The shaft m is actuated to traverse vthe structure or platform C by a squared extremity, such as m', and the meansA that a machine mounted in accordance with i our invention may be handled and directedv they] with the greatest smartness .and with less v fatigue, while any desired movement for the requiredcutting is obtainable with the mal chine, which is yet at all times firmly supf Y ported. The method of mounting and the carriage, indicated provide for, flrst,a free movement in avertical plane about a center; second, for a horizontal movement about a center, and`,'third., for a vertical adjustment,

of the percussive machine, and also, fourth, for a longitudinal adjustment of the platform supporting said machine upon the main car 'riage Y A. machine -mounted as herein described can be more readily transported about the mines, while its range of cutting and its' scope ofnsefulness are considerably extended. We also anticipate the saving of labor by mounting coal-cutting machines under our invention, while the machine operator is suhject to less risk.

We declare that what we claim isl. ln combination with a carriage for coalcutting machines, a vertical'shaft mounted thereon, said shaft rbeing screw-threaded, a screw-threaded sleeve fitting over said shaft and having a reduced upper end, a rotatable cap fitting over said reduced end and cutting mechanism carried by the cap.

2. ln combination with a coal cutting and winning machine, a carriage having an open framework, a platform fitting in said 'framework and having lianges thereon which enf gage the framework, means for moving the' IOC ` machl platform endwise on the' carriage, a vertical screw-threaded shaft carried by the pletform, a screw-threaded Sleeve fitting on said shaft,I and having a reduced upper end, a rotatable oep mounted on said reduced end and trunmensen seid cap for supporting the cuttingne. l e In testimony whereof We have signedl our names to this specification in the presence of two subscribing Witnesses.
